LINOTYPE-MACHINE.

Specification of Letters Patent.

Patented Ca; 2, 19L6 Application filed September 12, 1905. Serial Nc278,102.

To all whom, it may concern:

Be it known that LMELvIN W. MOREHOUSE, of Brooklyn, county of Kings, andState of New York, have invented anew and useful Improvement inLinotype-Machines, of which the following is a specification.

My invention relates to linotype-machines having the generalorganization represented in Letters Patent of the United States No.436,532. In these machines circulating matrices are carried in aremovable channeled magazine, from which they are released one at a timein the required order by escapement devices located at the lower ends ofthe channels and controlled by a finger-key mechan- 1sm.

Heretofore it has been customary to mount the escapement-levers andtheir pawls permanently in the lower end of the magazine, to

which the escapement-actuating springs were also attached in rear of theescapements, so that the escapements and attendant parts werenecessarily removed from the machine with the magazine.

The present invention relates to a construction in which the magazineand the escapement mechanism formingacontinuation of the same areconstructed as distinct members of the machine and independentlysupported, so that either may be removed independently of the other;also, that the one escapement mech anism may be employed in connectionwith a series of interchangeable magazines.

The invention consists in the arrangement and construction of partsdirected to this end and to the exact alinement of the magazine andescapement mechanism, as hereinafter explained.

Referring to the accompanying drawings, Figure 1 is a side elevationshowing the lower end of the magazine, the escapement mechanism, and theadjacent parts in operative positions. Fig. 2 is a similar view with themagazine removed, and Fig. 3 a similar view with both the magazine andescapement mechanism removed. Fig. 4: is alongitudinal vertical sectionfrom front to rear through the parts shown in Fig. 1; and Fig. 5, aperspective view, lookingat the lower left-hand cor ner, of the partsshown in the preceding figures.

In the drawings, A represents the rigid main frame, which may be of anyform and construction, provided only it is adapted to support theoperative parts hereinafter described.

B is an inclined base-frame for the magazine sustained by and forming,ineffect, apart of the main frame and intended to remain ordinarily in afixed position thereon. It may be varied at will, provided it is adaptedto sustain the magazine and the upper end of the escapement mechanism,as hereinafter explained.

0 represents the inclined channeled magazine seated on top of the frameB, from which it may be lifted at will in order to be replaced byanother containing matrices of a different font. It consists, as usual,of two parallel plates fixed to intermediate spacing-pieces and groovesor channels in their inner faces to receive and guide the edges of thematrices, as usual, although an equivalent construction may be adopted.

D represents the escapement -bar, so called, seated on the main frameand forming a continuation of the magazine. This bar is constructed withchannels corresponding to those of the magazine, through which thematrices are delivered into the usual front plate E, containing verticalchannels at which the matrices are directed to the usual assembling orcomposing mechanism. The escapement-bar D carries on its under side theescapements e, which consist of a centrally-pivoted lever having atopposite ends two pawls which are projected alternately upward into thelower side of the channels by the oscillation of the lever to permit thedelivery of the matrices one at a time in a manner well understood inconnection with the Mergenthaler linotype-machines of commerce. Theescapement-levers c are seated, as usual, in slots in the under side ofthe escapement-bar and are moved in one direction by springs e and inthe opposite direction by vertically-reciprocating reeds e ,urgedconstantly downward by springs 6 Fig. 1, of sufiicient strength toovercome the springs a, sothat the escapements stand normally in theposition shownin Fig. 4, with the lower or forward pawl elevated. Bymeans of the finger-key connections the reeds e are lifted and thespring 6' permitted to reverse the position of the escapement and toeffect the release of the foremost matrix F. The general arrangement andaction of the parts for actuating the escapement are the same as in theordinary Mergenthaler machine with the following exception: Heretoforethe actuating-springs have been located in the rear of theescapement-levers and the reeds eiwhich necessitated either theattachment of the springs to the magazine or the employmentofshortcoiled springs,which were unsatisfactory in practice. To overcome thesedifliculties and at the same time admit of the escapement mechanism as awhole being independently supported and independently removed, Iconstruct the escapement-bar D with a downward-extending flange Gr,located in front of the reeds e and their guide 6 To the lower edge ofthis bar D, I attach the lower coil ends of the springs e, which areextended upward and arranged to act on the forward face of an arm a,formed centrally on the escapement-lever e and extending downwardtherefrom, as shown. The form of the escapement-lever c, with itsdepending central arm 0 and the rear arm to engage the reeds c ,isoriginal with me, as is also the formation of the spring-supportingflange or web on the lower side of the escapement-bar. This constructionpermits the use of long and flexible springs and admits of the entireescapement mechanism, comprising the escapementbar D and theescapement-levers and springs, to be constructed, assembled, sustained,and removed wholly independent of the magazine.

The escapement mechanism may be sustained on the main frame in anysuitable manner; but I prefer to seat the upper edge of theescapement-bar D on the frame B adjacent to the lower end of themagazine, as shown at d. I As the bar and the magazine the channels ofwhich must exactly coincide are thus sustained where they meet upon oneand the same solid support, their exact alinement is insured. The loweror forward end of the bar D is preferably seated directly in the frontportion of the main frame, as shown at d. The bar being thus supportedat its upper and lower edges may be lifted from the machine at willwithout disturbing the magazine, and, on the other hand, the magazinemay be removed at will without disturbing the escapement mechanism. Theescapement-bar may be secured 'in place in any suitable rnanner-forexample, by providing it, as shown in Figs. 1, 2, and 5, at each sidewith a downwardly-extending ear (Z through which a horizontal pin d isinserted into the main frame. The withdrawal of these pins will releasethe escapement mechanism, so that it may be lifted from the machine atwill, the reeds 6 being first diconnected from the levers by swingingtheir guide 6 backward, as usual, around its pivot 6 In order to retainthe matrices in the magazine when it is removed from the machine, I v

propose to employ any suitable means independent of the escapementssuch, for example, as the flattened rock-shaft shown in United StatesPatent to P. T. Dodge, No. 7 7 6,779, or the removable bar such as shownin the United States Patent to J. RRogers, No. 786,156, as shown at M,Fig. 4 of the drawings herewith. 'What I claim as my invention is 1. Ina typographic machine, the combination of a main frame, amagazine'thereon, a channeled front plate fixed to the frame to receivethe released matrices,'and an intermediate independently removableescapement-bar seated on the main frame and provided with escapementsand with a depending flange carrying the escapement-spring.

2. In combination, the main frame, the magazine, the cooperatingescapement mechanism independently removable, and means distinct fromthe escapement mechanism to retain the matrices when said mechanism isremoved.

3. In combination, the main frame, the magazine seated thereon, and theescapementbar provided with the escapement mechanism and with thechannels, forming continuations of those in the magazine, said bar beingindependently removable at will, substantially as described.

4:. The main frame provided with the magazine, the front channel-plate Eand the reeds 0 in combination with the escapement-bar removably seatedon the main frame and provided with the escapements and with thespring-sustaining flange (Jr extended downward between the reeds and thechannel-plate, whereby the independent removal of the entire escapementmechanism is permitted.

5. In a linotype-machine, the main frame provided with the magazine andwith bearings d and d, in combination with the detachable escapement-barseated on said bear- 1ngs.

6. The escapement-bar channeled for the passage of the matrices andprovided with depending flange G, in combination with theescapement-levers having depending arms 6, and the springs e secured tothe flange and seated on the arms, substantially as shown.

. In testimony whereof I hereunto set my hand, this 6th day ofSeptember, 1905, in the presence of two attesting witnesses.
